1 Claim. (Cl. 252-857) This invention relates to compound fo ma nleather more durable.

An object of this invention is to provide a com pound of the characterdescribed for increasing the durability of shoes even if the shoes areused on such destructive ground as sand or rocks.

Another object of this invention is to provide a compound which ifapplied to leather will make it Waterproof and which may be applied onthe outside of the leather of shoes.

Still a further object of this invention is to provide a liquid compoundof the character described which may be applied with a brush, sponge orpiece of cloth freely in order to saturate surfaces of the leather tomake it durable and prevent deterioration.

Other objects of my invention will hereinafter appear in the followingspecification and the novel features thereof will be particularlypointed out in the appended claim.

The improved compound embodying the invention comprises the following:

Raw linseed oil, castor oil or cottonseed oil, between 55% and 75%;petroleum distillate solvent, known under the trade name Varnolene, 20%to 40%; pine tar, 3% to 7%; and benzaldehyde, 2 to 3 ounces per gallonof the liquid compound.

The above ingredients are mixed together in any suitable vessel and forma liquid compound which may be applied by brush, sponge or a piece ofcloth.

A good mixture can be made with the following proportions:

Raw linseed oil, castor oil or cottonseed oil, 65%; Varnolene, which isthe trade-name for a commercial petroleum distillate solvent, 30%; pinetar, 5%; benzaldehyde 2 to 3 ounces per gallon. The benzaldehyde servesas a deodorant.

The improved compound is useful to preserve leather transmission drivingbelts. In such case the leather must be saturated completely with theliquid compound.

In general, any kind of leather Will be improved many times in itsdurability by full saturation with said compound.

New soles, if they are shellacked, must be worn a couple of days beforeusing the compound, if desired however, the new soles can be sandpapered with fine sand paper in order to remove the shellac or varnishand then they can be saturated with the compound.

The saturation must be repeated as often as possible, but once a weekhas been found suflicient.

It will thus be seen that I have provided a composition in which theseveral objects of this invention are achieved and which are adapted tomeet the conditions of practical use.

As various possible embodiments might be made of the above invention,and as various changes might be made in the embodiment above set, forth,it is to be understood that all matter herein set forth, is to beinterpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

A compound for improving the durability of leather, comprising a mixtureof raw linseed oil about sixty-five percent, petroleum distillate knownas Varnolene, about thirty percent, and pine tar about 5 percent,combined with benzaldehyde in the proportion of two ounces of the latterto one gallon of the former mixture.
